SPECIFICATION forming part of Letters Patent No. 632,830, datedSeptember 12, 1899.

Application filedNovember 25, 1898. Serial No. 697,446. (No model.)

To all whom, it may concern:

Be it known that I, GEORGE BETZONICK, a subject of the Queen of GreatBritain, residing at Sydney, in the Colony of New South Wales, haveinvented certain new and useful Improvements in Samplers; and I dohereby declare the following to be a full, clear, and exact descriptionof said invention, such as will enable others skilled inthe art to whichit most nearly appertains to make, use, and practice the same.

This invention relates to improvements in samplers; and it consists inthe combination and arrangement of the parts as hereinafter fully setforth and described.

It consists in providing a hand-press for extracting the juice fromdifferent materials to test the juice for desired qualities after theyhave been pressed.-

It further consists in providing a cutter or extractor by which smalland regular samples of material to be tested may be taken and deliveredinto the body of the press.

It further consists in the novel arrange ment by means of which thesampler or juicereceptacle may be attached to or packed with the press;and it further consists in the novel construction and arrangement of theparts, whereby they can all be separated for the purpose of cleaningthem.

In the drawings, Figure l is a side view of the invention. Fig. 2 is avertical section of the same, the circular cutter and separator being inposition. Fig. 8 is a side View of the outer shell of the press-chamber,the bottom being detached. Fig. 4. is a side view of the perforatedinner cylinder of the pressing- Fig. 5 is a side view of thepresserscrew, the detachable handle and piston-head being detached andconnected by dotted lines.

The pressing-chamber is constructed of two cylinders A and B. The formeris solid walled and is connected by a suitable screwthread at the bottomto the cap C and at the top to the threaded cap D. A short spout oroutlet E is let through the wall of this cylinder near the top thereof.The cap Q is secured to the lower end of the cylinder by an internalscrew-thread, while the cap D is connected to the chamber by an externalscrewthread. The inner or perforated cylinder B is formed integrallywith the cap D and is open at the bottom,where it is provided with acouple of pins F to receive the bayonetslotted extension of the circularcutter G. When the two cylinders are mounted in position, they areseparated by a space, as shown in Fig. 2. They are locked againstmovement by a set-screw H, which is mounted in threaded perforations letthrough the outer cylinder and guided to enter the perforation let intothe side of the cap D.

Through the perforations in the top of the cap D extends ascrew-threaded plunger I. This is provided in its operative form withthe presser-head J, to which it is attached by means of a stud 1',formed on the end of the plunger I. To place the head J in position, thescrew is driven down through the inner cylinder until the end protrudesat the bottom, when the stud I may be inserted into the undercut slot Jin the head J. Then the plunger I is drawn upward, the head J is carriedinto the inner cylinder and prevented from being dislodged from theplunger, which forms a neat fit with and a guide for the plunger I. r

In its operation the device. is mounted so that the plungerI iswithdrawn to its full capacity and secured in position by means of theset-screw 1 The circular cutter G and separator G are then mounted uponthe end of the inner cylinder, the bayonet-slots G of the same fittingover the pins F on the inner cylinder. The inner diameters of both theinner cylinder and the circular cutter are approximately parallel. Ifthere is any differerence, it is that the diameter of the cutter shouldbe slightly less than the diameter of the inner cylinder 13. Thedetachable. ring G with which the cutter is provided, is set so as toregulate the depth to which the cutter will extend. The instrument isnow grasped, and the material to be sampled is punctured by pressingwith a rotary movement the circular cutterinto the material.

\Vhen using the instrument in the class of work for which it is atpresent designed-that is, the testing and sampling of sugar-caneit isoften found that the skin of the cane is hard, and the best method ofcutting the skin is to rotate the cutter until the skin has been penetrated. It will then be found that by a steady direct pressure thecircular cutter can be forced into the cane with little resistance untilthe regulating-ring G rests upon the cane. When, now, the instrumentisrevolved steadily in one direction, the blade G, which is formed in theinner surface of the circular cutter, will force the material within thecircular cutter to separate the plug of the material within the cutter,and when the cutter is withdrawn this plug or sample of the materialwill be withdrawn with it. This operation is continued until the innerchamber is filled with various plugs or samples, or, in some instances,when it is only partly filled.

In the sampling or testing of sugar-cane, for which, as before stated,this invention is particularly designed, various qualities arediscovered at various heights in the cane, and it is desirable to obtainsamples from all varieties of the cane with reference to the height towhich the cane has grown. By doing this and taking an equal number ofsamples from various heights it is found that the general quality of thebulk of the cane being sampled is best arrived at.

WVhen the chamber has been filled with plugs, as hereinbefore described,the circular cutter G is removed and the cap 0 is screwed into positionuntil the rubber gasket 0 at the bottom makes a tight joint with thebottom of the outer cylinder A.

To steady the device during the operation of pressing the cane, theforked arms 0 are inverted from the position shown in Fig. 1 of drawingsto that shown in Fig. 3. This provides two arms, which may be straddledover a piece of fallen cane or other suitable material, and theset-screw I being relieved and the handle I placed in position theplunger I and head J are forced down upon the samples contained in theinner cylinder B. This is continued until the juice has been pressed outof the samples, in doing which the juice will pass through theperforated sides of the inner cylinder 13 into the space between the twocylinders A and B. When sufiicient pressure has been exerted within thejudgment of the operator to extract all or as large a portion of thejuice as desired, the cylinders are emptied by pouring the juice out ofthe spout E into the juice-holder K. The saceharimeter L is now placedin the juice to test it. To prevent spilling of the juice during theoperation of pressing the same, the juice-receptacle is provided withthe ears L L by means of which it is mounted upon the sides of thecylinder A, as shown in Fig. 1. When the operation has been completed,the parts may be separated, as shown in the drawings, and cleaned. If,however, several samples are desired, the operation may be repeated, asdescribed, by unscrewing the cap 0 and ejecting the plugs or samples byforcing down the plunger I in the manner described.

For the convenience of handling this instrument it is particularlydesigned to be packed within small and compact space. For this purposethe bottom of the juice-receptacle K is provided with pins L extendedout from the side upon which the circularcutter is mounted, as shown inFig. 1. The handle I is removably attached to the plunger I, so that itmay be packed separately.

Having thus described this invention, it is claimed 1.
